This patch corrects a number of minor errors in the Ebony device tree:
	- Missing (given as 0) cache sizes are added to the CPU node
	- device_type properties are removed from nodes which don't
have a reasonably well defined device_type binding.  This does require
a very small code change to locate the busses to be probed for
of_platform devices by 'compatible' instead of 'device_type'.
	- A node is added for the SRAM controller
	- The unit address of the small-flash node is adjusted to
correctly reflect the reg property.
	- device_type values for the MAL and ZMII are updated to
reflected more up-to-date versions of the binding.
	- An incorrect offset in the partition map for the large-flash
node is corrected.
	- Some redundant values, already commented out are removed
entirely.
